Medical packaging materials include wax, glass, ceramics, paper (board), rubber, metal, etc. Among them, glass has a long history of being used as product packaging and is the preferred packaging material for many beverages such as beer, fruit tea, and jujube juice. In the field of medical packaging, glass packaging materials are widely used for the packaging of injections, biological drugs, blood products, and oral liquids.
In addition to the above-mentioned traditional packaging materials, plastic packaging plays an increasingly important role in the pharmaceutical field. As a packaging material, plastic has many excellent properties such as high strength, good barrier properties, light weight, easy to carry, and transparency, thus becoming the main material in modern medical packaging.
1. Medical plastic bottles. The types of plastics used in practice include polyethylene (PE), polypropylene (PP), polystyrene (PS), polyester (PET), etc. PET is a material that has entered the medical plastic bottle market in recent years.
It has high transparency, which allows you to see whether the medicine has deteriorated, and its moisture barrier performance is particularly excellent, which greatly facilitates the preservation of medicines; it is easy to color or add some additives to meet special requirements (ultraviolet light blocking).
2. Rigid film. It is usually made into small bags for medical packaging applications. Plasma bagging is the most typical example of using composite film to package medicines. Breathable film plays an important role in the packaging of bone-attaching drugs.
3. Blister packaging of sheets and tablets is a popular packaging. The main materials used are aluminum foil, adhesives and plastic sheets; and plastic sheets are mainly polyvinyl chloride (PVC) sheets and polyester (PET) sheets. Alu PVC blister packaging is used for many drugs.
Polyvinyl chloride (PVC) sheets require non-toxic formulas; the content of ethylene oxide (VC) in PVC resin is less than 1X10-6. Polyester (PET) sheets are used for pharmaceutical packaging after PVC sheets, and after some European countries banned PVC for disposable packaging, it has become the main sheet for pharmaceutical packaging.
PTP aluminum foil is an important packaging material with excellent quality. It is made by rolling electrolytic aluminum. It is very ductile and has uniform thickness. It is often used in the packaging of tablets, capsules, and granules. As packaging aluminum, its thickness is less than 0.2mm.
